PSC M1BZ

Overview

The Product Service Code (PSC) is a government-wide, four-character classification system that identifies the goods and services acquired by federal agencies for reporting, spend analysis, and category management. PSCs are the primary "what" field recorded in FPDS and SAM and are governed by the FPDS/Product Service Codes Manual maintained on Acquisition.gov. ¹

PSC M1BZ is an M-series logistics/facility PSC used to classify the operation of airfield-related facilities that are not runways or terminals. The PSC Manual lists M-series facility operation codes but does not publish a detailed, item-by-item operational definition for M1BZ; agencies assign and apply the code to specific solicitations and awards per local acquisition requirements. Not specified by official sources. ¹

What this PSC covers

• Airfield operations support and facility management, applied to non-runway/terminal facility operations. ¹
• Operation of non-runway airfield structures (for example, hangars, aprons, lighting structures). ¹
• Airfield safety and operational monitoring duties associated with facility operation. ¹
• Airfield equipment operation and coordination (non–air-traffic-control equipment). ¹
• Administrative records and reporting related to airfield facility operations. ¹

Related NAICS and PSC codes

Official, agency-level PSC→NAICS crosswalk entries for PSC M1BZ are not published as a single, prescriptive mapping in the PSC Manual; agencies commonly select the NAICS that best describes the predominant work for each procurement, so mapping varies by solicitation and award. Not specified by official sources. ¹

Reporting & category management

M-series PSCs (facility and operations) are captured in FPDS and often drive service-contract inventory reporting and category alignment used by agencies and OMB/GSA category managers; FPDS records and definitions describe PSC roles in award reporting. ³

Agencies must select the PSC that best represents the predominant service on an award for FPDS reporting; some M-series PSCs and reporting expectations are referenced in DFARS/PGI guidance for service inventory and PSC reporting. ²

Frequently asked questions

• What is the exact official text for PSC M1BZ?
  The PSC Manual identifies M-series facility operation codes and lists M1BZ as the operational category for other airfield structures, but it does not publish a granular, prescriptive activity list for the code. Contracting officers apply the code by solicitation/award context. ¹

• Which NAICS should be used with PSC M1BZ?
  No single NAICS is mandated for M1BZ in the PSC Manual; contracting officers select the NAICS that best fits the predominant work in each procurement, so practice varies by acquisition. ¹

• Are M1BZ actions reportable in the System for Award Management service-contract inventory?
  Service contracts that meet statutory thresholds and use M-series PSCs are subject to mandatory service-contract inventory and related reporting; check DFARS/PGI and agency guidance for thresholds, portfolio lists, and reporting mechanics. ²

• Where is the authoritative PSC list and where are updates published?
  The authoritative source for active PSCs and code changes is the FPDS/Product Service Codes Manual on Acquisition.gov; FPDS and Acquisition.gov host the official PSC list and any updates. ¹
